Use this option to define reinforcement laps (connections of reinforcing bars) if a reinforcement length exceeds the value defined in the preferences (e.g. 12 000 mm). After selecting the Lap splice tab, the Reinforcement: definition and detailing - radial reinforcement dialog displays:
The options provided on this tab allow you to:
- Determine if bars should be with or without laps
- Specify parameters of bars with laps.
If the Bars without lap splices option are selected, then reinforcement laps are not used in a reinforcement distribution. Bars will be distributed in such a way so that they fit the distribution region, but without considering the maximum length of bars (single bars in the distribution may be longer than Lmax) and without lap splices. The reinforcement table includes information about the total length of distributed bars multiplied by a factor defined in the Job preferences dialog box (the Options tab).
If the Bars with lap splices option is selected, then reinforcement lap splices will be created during reinforcement distribution.
The following parameters of reinforcing bar laps are defined:
- A lap length (the proposed value is a multiple of a reinforcement diameter)
- An offset value when laps are arranged in the passing manner.
Definition of positions of Z laps involves changing the lap position (a mirror reflection with respect to the bar center).
